The power system is built with 12 independent 48V50Ah battery modules. Each battery moudle is with 2.4Kwh. Power Mode
Schematic Diagram: controlled by Time Relay
Equipment Connection Newly Proposed Solution:
BP4850B LFP battery modules is selected
Performance
Parameters (single unit of BP4850B modules): Original Configuration:
Note: Calculated with 30 days per month.
Ø The site will down-time happen because of Diesel Gen-set start failure.
Ø The DG without Dry Contact Signal to control it start if the battery power finish but the time still not reach 2 hours. à Also down time happen. Lead-acid batteries’ capacity drop down so fast because of high temperature.
Ø The DG load is only 34%, has serious Low Load Problem. It will reduce the engine life!
Solution: 12 pcs BP4850 battery modules.
Dimensioning
Solution:
lUse Current-Limiting Mode of the BP4850B battery to
protection:
Ø The
current of charging is limiting within 10A.
Ø The BMS of battery can give over-current
protection during the system start.
Ø Higher the system stability.
Ø Longer the battery’s cycle life.
l 3
hours batteries’ capacity for backup:
Ø Most
of power failure caused of DG Start Failure. It needs some power backup for
rush repair;
Ø For LFP battery it is good has 80% DOD for
longer Life Cycle;
